A Roften House is a rare 1960s system-built property defined by flat roof construction, steel framing, and asbestos-cement wall panels. While distinctive in design, these homes require careful inspection due to risks associated with roof durability, corrosion of metal components, and the presence of asbestos-containing materials.

The Riley House is a rare non-traditional property type developed in the 1940s to address post-war housing shortages. Built using a steel frame with lightweight external wall construction and asbestos-containing roof coverings, these houses require a condition-led approach to inspection. Corrosion to steel elements and the management of asbestos materials remain the primary technical considerations when assessing a Riley House for purchase.

Resiform houses are a very rare form of 1960s system-built housing, constructed using glass fibre reinforced resin wall panels backed with asbestos cement. Built in extremely limited numbers, they sit firmly within the non-traditional category and require careful inspection, particularly in relation to panel condition, moisture performance, and asbestos management. A detailed building survey is essential to understand their construction-specific risks and long-term maintenance implications.

The Reith House is a rare form of non-traditional housing dating from 1926, constructed using early steel panel systems rather than traditional masonry. Manufactured by John Cran & Somerville Ltd, only four examples are believed to have been built. Their condition today is heavily dependent on the performance of protective coatings to the steel structure and the condition of concealed timber and fibreboard linings, making careful inspection essential.

The Quality House is a post-war, non-traditional property developed in 1945 using steel-framed construction and flat roof detailing. While distinctive in appearance, these homes present specific inspection considerations, particularly around steel corrosion, flat roof performance, and the potential presence of asbestos-containing materials. A detailed building survey is essential to properly assess condition, refurbishment history, and associated risks before purchase.

A Portal Temporary Bungalow is an exceptionally rare form of post-war prefabricated housing, constructed in 1944 using pressed steel components as an emergency response to housing shortages. While historically significant, its long-term condition depends heavily on corrosion control, moisture management, and informed inspection of the original steel structure.

Phoenix Temporary Bungalows are post-war, non-traditional dwellings constructed between 1945 and 1948 using steel framing and asbestos cement panels. While historically significant, their construction places particular emphasis on frame condition, corrosion risk, and the management of asbestos-containing materials. A focused building survey is essential to understand the practical risks associated with this property type.

The Paragon House is a rare post-war, system-built bungalow developed by J & J Weir Ltd around 1945. Identified by its U-shaped layout, flat steel roof, and steel-clad walls, its long-term performance is closely linked to corrosion control, roof condition, and ongoing maintenance of its non-traditional construction.

Open System Building houses are a distinctive form of non-traditional housing constructed between 1967 and 1970 using precast reinforced concrete components. Typically arranged as two-storey terraced or semi-detached homes, their long-term performance depends heavily on the condition of PRC panels, structural frames, and bearing details. A thorough building survey is essential to identify cracking, bowing, and other construction-specific risks before purchase.

The Nissen-Petren house is a rare interwar, non-traditional property defined by its distinctive curved steel roof and steel-framed construction. With only a small number built, careful inspection is essential, particularly in relation to corrosion risk, roof condition, and long-term maintenance of the steel structure.

The New Georgian house is a rare post-war residential form developed during the 1940s, combining traditional Georgian styling with modern steel-framed construction. Built in very limited numbers by A Robert’s & Co. Ltd, these properties appear conventional externally but rely on concealed structural systems that require careful inspection, particularly in relation to corrosion protection and moisture control.
